S&S Cycle Cruise Control Brackets for Super E & G Carburetors - Manual (Page 2)

INTRODUCTION
S&S
® Cruise control brackets for Super E&G Carburetors are
designed for use on big twin & Harley-Davidson ® Twin Cam 88 ®
model engines.
These brackets in conjunction with S&S E&G carburetors will
work with factory cruise control systems on Harley-Davidson
®
motorcycles.
THIS INSTRUCTION SHEET SHOULD BE USED IN
CONJUNCTION WITH S&S SUPER E&G CARBURETOR
INSTRUCTION SHEET 51-1012.
Throttle Cable Requirements
These brackets are designed to use stock Throttle Cables from
1993 up Harley-Davidson
® motorcycles.
Gasoline is extremely flammable, explosive under certain
conditions, and the fumes toxic when inhaled. Disconnect
battery ground cable before installation to prevent sparks, do
not smoke around gasoline, and perform installation in well
ventilated area away from sparks or open flame.
If motorcycle has been running, wait until engine and exhaust
have cooled to avoid getting burned during installation.
A. Remove the seat and disconnect the battery. See Harley-
Davidson ® service manual for proper procedure.
B. Remove fuel tank from motorcycle. See Harley-Davidson ®
service manual for proper procedure.
C. Remove carburetor from motorcycle. Refer to carburetor
instruction sheet 51-1012.
1. Once carburetor is removed and drained of all fuel,
remove the top cable guide assembly.
2. Using a small screw driver adjust idle speed screw out
until it is just touching throttle spool stop with the
throttle plate closed. See Picture 1.
3. Holding the carburetor firmly, remove throttle shaft
nut and lock washer on throttle spool side of
carburetor. Making sure the spool and return spring
don’t come off the shaft. Install new cruise control
arm
on throttle shaft with eyelet arm facing out.
See Picture 2. Re-install lock washer and new thin
nut 50-5027 supplied in kit. (Do not torque nut yet.)
Adjust idle speed screw so it allows throttle plate to
fully close in the carburetor bore. Carefully loosen
(DO NOT REMOVE.) throttle plate screws. Once
screws are loose, torque nut to 40 in-lbs.
Over tightening throttle shaft nut can cause irreversible
damage to throttle shaft and nut.
NOTE: When you torque the throttle shaft nut the throttle plate
will open, let it open until it hits the throttle stop on the
carburetor body. make sure you don’t let it snap shut, let it close
slowly so you don’t damage the bore of the carb body with the
loose throttle plate.
4. Re-center the throttle plate in the bore of the
carburetor. carefully move throttle plate so it centers in
the bore of the carburetor body. (With the throttle
closed you shouldn’t see any gaps where the throttle
plate and bore meet.) Once it is centered, remove one
screw at a time and apply a very small drop of Loctite
®
242 or equivalent to threads and tighten screws. Once
screws are tightened, check to make sure throttle opens
and closes without binding. Throttle should snap shut. If
it binds repeat this step.
5. Readjust idle speed screw . Turn screw counter clockwise
until it no longer contacts throttle linkage spool. Next
turn screw clockwise until it just contacts spool. Then
turn additional 1⁄2 turn clockwise to slightly open
throttle plate.
